“For personal reasons, I've checked myself into a rehab clinic. With 2011 being a busy year for Backstreet, I want to be healthy and perform and sing for people at my very best and happiest. None of this will affect our current tour plans and I look forward to seeing everyone really soon!” He added, “Thank you for all of your support and respecting my family and friends privacy during this time.”
He also tweeted:
